This read action is giving me the above error message, after migration to Ash 3.0. If it’s relevant, key is the source and destination attribute name for Resource1’s belongs_to relationship.

key = "1234"
Resource1.read_by_key!(key)

Resource1


actions do
    default_accept :*
    read :read_by_key do
      argument :key, :string

      filter expr(key == ^arg(:key))
    end
...

code_interface do
    domain ...
    define :read_by_key, action: :read, args: [:key]

...

Should it be action: :read_by_key?

That works. Thank you! I misunderstood action: is to specify the type of action (:read, :create, etc.) rather than the name of specific function.

The doc says action: defaults to the same name as the function which led me to think

define :read_by_key, args: [:key] should work

instead of

define :read_by_key, action: :read_by_key, args: [:key]

But it doesn’t because action: is not optional. What does the Doc mean about the default here?

Name:  action
Type:  atom
Docs: The name of the action that will be called. Defaults to the same name as the function.

I’m 99% sure that action is optional. What makes you say that it’s not optional? Do you get a required error if you don’t specify it?

Never mind. There was a typo. :frowning:
